HUMANAE VITAE
ENCYCLICAL OF POPE PAUL VI ON THE REGULATION OF BIRTH
JULY 25, 1968
To His Venerable Brothers the Patriarchs, Archbishops, Bishops and other Local Ordinaries in Peace and Communion with the Apostolic See, to the Clergy and Faithful of the Whole Catholic World, and to All Men of Good Will.
Honored Brothers and Dear Sons, Health and Apostolic Benediction.
The transmission of human life is a most serious role in which married people collaborate freely and responsibly with God the Creator. It has always been a source of great joy to them, even though it sometimes entails many difficulties and hardships.
The fulfillment of this duty has always posed problems to the conscience of married people, but the recent course of human society and the concomitant changes have provoked new questions. The Church cannot ignore these questions, for they concern matters intimately connected with the life and happiness of human beings.
